Good rechargeable batteries - 4AA for $9

Amazon is selling rechargeable batteries called Sony Cycle Energy for $9, which are the best rechargeable batteries available.  Unlike most rechargeable batteries that lose all of their charge in a few weeks, these batteries retain 85% of their charge after 1 year, so you don't have to recharge them as often (perfect for your remote control!).  Sony uses the same technology as Sanyo Eneloop batteries, which are about 1/3 more expensive right now.
